Compact fluorescent lamps (CFLs) use about one-third the energy of incandescent lamps and last about ten times as long. Learn how you can save energy and money by making the right CFL choice for your application.

Track lighting provides directable beams of high-quality light for use in retail displays, galleries, museums, and residences. Learn about the many energy-efficient options now available to help you make the right choice for your application.

Electronic fluorescent ballasts offer both performance and energy-efficiency improvements over typical magnetic versions. Learn the differences between ballast types and the potential to save energy and dollars for your application.

Confused about how to identify and understand the differences between the myriad available fluorescent lamps on the market today? Learn to make sense of the confusion and determine which lamp best fits your application.

High-intensity discharge (HID) lighting offers very high efficiency and energy savings of 50 to 90 percent over incandescent sources, but the options can be confusing. Learn about performance characteristics and energy consumption so you can determine which type is best for you.

Indirect lighting, in which light is mainly distributed upward rather than directly onto a work surface, minimizes glare on computer screens and creates a soft, inviting environment for concentrated work. System design can be challenging; find out what you need to know to make the right decision.

Light-emitting diode (LED) technology continues to improve; these lamps are becoming more common in business settings. Learn about the best applications and potential energy savings for this emerging and increasingly cost-effective technology.

Lumen depreciation, an indication of the decline in lamp light output over time, is an important performance characteristic that varies with lamp type and fixture cleanliness. Learn about the depreciation of various lamp types and the benefits of keeping them clean.

Lighting controls are primarily used to turn lights off when they are not needed or dim them so that they produce no more light than necessary. Learn about the various options so you can choose the right system for your application.

Occupancy sensors have the potential to cut energy consumption by reducing the operating time and output of lighting systems,but a wide variety of issues need to be considered in order to achieve persistent savings. Learn about the factors you need to know before installing an occupancy sensor.

Although magnetic ballasts are still typically used with metal halide lamps, electronic ballasts are now coming on the market and offer a host of performance and energy benefits. Find out how to choose the best ballast for your metal halide lamps.

Preferences for lighting levels vary widely in commercial buildings and personal dimming systems now make it feasible for individual workers to control lighting levels in their personal workspaces. Find out how these systems work and if they are right for your application.

Power reducers are a retrofit option for cutting energy costs in a fluorescent or high-intensity discharge lighting system, and though they reduce energy costs, they simultaneously reduce light levels. Find out if this retrofit efficiency technology is right for your application.

Although it is often less efficient than conventional lighting systems, remote-source lighting systems (often referred to as fiber-optic or light-pipe systems) have some unique performance characteristics. Find out how these systems operate and whether they would benefit you.
